The BQ77905 is a 3-5S low-power protector for lithium-ion batteries that controls the charge anddischarge FETs for current control. In some cases, the charge and discharge current path is required tohandle a continuous high-current that causes heat and component problems. This document provides anexample of the BQ77905 with a 50-A current path for charge and discharge. The design considerati - bq77905 Separate Current Paths (Rev. A)PDF, 253 Кб, Версия: A, Файл опубликован: 7 июл 2016
The basic implementation of the bq77905 3-5S Low Power Protector for lithium-ion batteries uses a singleseries current path for charge and discharge. In some system designs it is desirable to have separatecurrent paths for charge and discharge. This document shows circuit implementation examples ofseparate charge and discharge paths when using the bq77905. The schematic examples and test res
